,Chapter 1. Perfusion
1. 1. A patient with suspected hypovolemia has cool skin, a rapid weak pulse, and delayed capillary refill. Which
finding requires the most immediate nursing attention?
A. Urine output of 45 mL/hr
B. Heart rate of 132/min with worsening mental status ✓
C. Mild thirst
D. Capillary refill of 3 seconds
Answer & Reasoning:
Correct Answer: B
Explanation: Rationale: The combination of tachycardia and worsening mental status suggests inadequate systemic perfusion and
possible progression toward shock.
Exam Tip: Select the option that best addresses the priority clinical problem and patient safety.
2. 2. A patient taking an antihypertensive reports dizziness when standing. Which nursing instruction is most
appropriate?
A. Stand quickly to improve circulation
B. Change positions slowly and sit if dizzy ✓
C. Restrict all fluids
D. Stop the medication immediately
Answer & Reasoning:
Correct Answer: B
Explanation: Rationale: Slow position changes reduce the risk of symptomatic orthostatic hypotension and falls.
Exam Tip: Select the option that best addresses the priority clinical problem and patient safety.
3. 3. Which assessment best reflects peripheral arterial perfusion?
A. Bowel sounds
B. Pedal pulses and skin temperature ✓
C. Pupil size
D. Bowel elimination pattern
Answer & Reasoning:
Correct Answer: B
Explanation: Rationale: Pedal pulses and extremity temperature provide direct information about arterial blood flow to the limbs.
Exam Tip: Select the option that best addresses the priority clinical problem and patient safety.
4. 4. A patient with chest pain becomes pale and diaphoretic. Which assessment is the priority?
A. Pain history only
B. Perfusion and hemodynamic status ✓
C. Dietary preferences
D. Sleep pattern
Answer & Reasoning:
Correct Answer: B
Explanation: Rationale: Pallor and diaphoresis can accompany impaired cardiac output; circulation and hemodynamic stability
must be assessed promptly.
Exam Tip: Select the option that best addresses the priority clinical problem and patient safety.
5. 5. Which laboratory result is most concerning in a patient with a suspected severe perfusion deficit?
A. Lactate 5.2 mmol/L ✓
B. Hemoglobin 14 g/dL
C. Sodium 139 mmol/L
D. Glucose 96 mg/dL
